The stock front pipe have a cat on it and should normally help reduce the borla uel headers noise a bit but will also reduce the exhaust flow and so the hp by the way.
I'm pretty sure that the combo of a Perrin resonated cat-back + borla UEL headers would be a perfect match and perfect music to my hear.
I like what I saw here on the video but for me it is a bit too noisy for long term use.

Yeah, resonated and front pipe catted will certainly be one of the top sounds you will hear with this setup.
I'd be interested to hear someone who has a catted front pipe, unresonated on something like the V1 or the Perrin. Definitely don't expect these guys to do all these tests with the headers. Give it a few weeks and other people who purchase the header will start posting their videos/reviews of the UEL header with several exhausts.
Awesome videos btw Jeremy. You showed just about every aspect of this header you can. It's pretty loud at highway cruise ~70 mph. One of the reasons I'm considering a Hemholtz resonator in my exhaust which I believe combats that frequency some. Hell, I don't mind that sound since I love my cars loud. Sounds absolutely awesome.
